The ST25 is an all-new digital audio player expertly crafted in Cambridge, UK. It is more than a successor to the award winning ARCAM ST60 streamer, with an all-new digital audio and streaming platform, new linear toroidal power supply design, new user interface and new app.

Exquisite sound quality has been achieved through thoughtful engineering of a new 6-layer digital audio and streaming platform which includes a ground plane through the entire board to keep noise and interference away from the sensitive audio components. These components include the latest Hyperstream iV DAC topology from ESS, in a balanced configuration with advanced Jitter elimination. Sound quality is enhanced further with a new linear toroidal transformer power supply design that drives the entirety of the internal operation with lower noise, and a switching supply that only operates for peak efficiency when in standby.
